Ariwara

The Ariwara was a feudal samurai clan founded in 825 when Ariwara Narihira, the grandson of emperors Heizei and Kammu, was given his own clan name after becoming relegated to civilian life. Thus, the clan was descended from the Minamoto clan. In 1188 they were given Bitchu Province after the Kamakura Minamoto took it from the Kobayakawa.
